Insert

Abstract

An insert, which can be installed as an odor stopper in the drain area of a household installation, e.g., in a drain pipe, includes a cylindrical area, which has a flange that projects outward. The insert also includes a closure area with an elastically deformable wall part. In the closure position, the wall part of the closure area rests against an opposite wall of the insert. In this case, the free edge of the wall part rests against the opposite wall from inside, creating an odor stopper. When water flows through the drain pipe, the wall part of the closure area is moved away from the opposite wall by the draining water, so that the closure area is opened. As soon as no more water flows through the insert, the wall part of the closure area again rests against the opposite wall, so that the odor stopper is created.
